With LLM agent writing ultra vvverbose code, golf coding is more important than ever.

It's kind of funny that it took me several years to realize that GitHub (GH) is the reverse of Mercurial (HG) 🙃 If I were using GitHub CLI, I would have noticed that sooner because of typos ... gti is my most command not found 😅

Posted Part 2 of Scaling Rails at Aura Frames on Lobsters, and it's doing pretty well. If you're active there (or HMU for an invite), please take a look. Thanks! lobste.rs/s/zijb20/sca...

Quick PSA: If you're an event organizer who wants the Ruby Passport at your event, get in touch with me at least one month in advance. These things take a while to get made and shipped your way. ✌️

What a promising day of ski !

I asked to a LLM to write my prompt. The circle is complete.

This Wednesday: discover how to calculate your ideal concurrency level before running a single benchmark with Alexis Bernard from RoRvsWild — no guesswork, just smart statistics. 🚀 meetu.ps/e/PPF4y/KFPP...

How to determine the optimal concurrency level for a Rails app on the first try, Wed, Feb 11, 2026, 7:00 PM | Meetup

***👉 Notice to attendees*** *The event will be held **in a different room** than usual. We will meet in room **011** of the **main building** of the UOG, on the **1rst fl

If you update or delete often rows watching bloat tables and indexes is important. This article is a great explanation and I also recommend using the gem rails-pg-extras to watch bloat ratios: github.com/pawurb/rails...

Nice post! Via Creston Jamison / Scaling Postgres podcast VACUUM Is a Lie (About Your Indexes) boringsql.com/posts/vacuum...

One thing I'm really excited about in Ruby 4.0 is that object allocation is going to get a nice speed boost

Tonight I will be presenting at Geneva.rb on how to protect a web application against bots and brute force attacks without annoying humans and **without relying on a third-party service**.

Next Wednesday I will give a presentation at Zurich.rb, and then on the 19th November at Geneva.rb: How to protect web applications against spam bots and brute force attacks without annoying humans, and why I think captchas are not the best solution.

AI can write tests, but it doesn't understand what truly matters to you, your product, or your codebase. Without guidance, it follows patterns, and the output feels sometimes good, sometimes bad. That's why I'm launching a new workshop: Reliable Test Case Generation with AI.

If your are unsure about adding a new column to a table or creating a new model, always create a model. Your code base will thank you. Let's have a look to the User model.

TIL: In SQL the RETURNING instruction accepts any expression, not only a column name. That seems so obvious, but I took all that time to notice it 😅

6 spots filled, 9 remaining for the Good Enough Workshop this Friday at 15:00 UTC Here are all the details about the workshop. In case you have questions reply here or via email -> hello@goodenoughtesting.com

I tried to explain why I don't believe the recent accusations toward my former teammates, as well as how the Ruby and Rails Infra team at Shopify operates and why it can be trusted. byroot.github.io/opensource/r...

I am very happy to have become dual citizen 💎 since last @euruko.org. Thanks @adrianthedev.com and @avohq.io 😀

Switched to ReActionView in production! Deploy on Friday and go away 🙃

So using Ruby, what is the largest Fibonacci number we can calculate quickly? This article is a deep dive into the world of Fibonacci numbers to show some really neat tools that Ruby provides. www.rorvswild.com/blog/2025/fi...

Developers who remove lines of code are the ones who maintain a project's productivity. Those who frantically add lines of code sabotage it.

“If this test fails, would I care or just ignore it?” “If this works, what does it prove?” “If this fails, do I know why?” If a test doesn’t help you think better, it’s noise. More on this mindset → Aug 1 workshop goodenoughtesting.com

Good Enough Testing

A practical workshop that will show you a series of test design techniques, providing a systematic and repeatable approach to write test cases

I knew that handling time in programming is hard, but not that hard: shanrauf.com/archive/how-....

Do yourself a favor and buy a programming book in addition to your AI subscription. One is consumption, the other is investment in yourself. You will get more skilled at the end.

Internet must remain decentralized. Cloudflare is the easy choice to protect your website, but it has a hidden cost. It controls which trafic goes to your website and can read it. This price is too high for me, and for you too. torrentfreak.com/cloudflare-c...

Cloudflare CEO Matthew Prince says he "Pray no one dies" after revealing that piracy blocking denies access to critical resources in Spain.
